Venous access port with molded and/or radiopaque indicia
First Claim
1. A venous access port assembly for implantation into a patient, comprising:
- a housing comprising;
a base defining at least one reservoir; and
a peripheral surface adjacent to the at least one reservoir and extends outwardly from the base about a perimeter of the at least one reservoir, the peripheral surface comprising X-ray discernable indicia configured to indicate, under X-ray examination, that the assembly is rated for power injection, wherein the peripheral surface is comprised of X-ray discernable material, and wherein the peripheral surface further comprises a top surface, a bottom surface, and one or more voids extending through a height of the peripheral surface from the top surface of the peripheral surface to the bottom surface of the peripheral surface; and
a needle-penetrable septum communicating with the housing;
wherein the base has a bottom outer surface including at least one of the X-ray discernable indicia within a region directly beneath the at least one reservoir, wherein the X-ray discernable indicia are the one or more voids in the peripheral surface and are comprised of the X-ray discernable material.

Abstract
A venous access port assembly having a base, a peripheral surface, and a septum. The base defines an interior reservoir. The peripheral surface includes integrally molded X-ray discernable indicia identifying that the assembly is rated for power injection. The X-ray discernable indicia may extend through a height of the peripheral surface from a top surface to a bottom surface thereof. According to one aspect, the peripheral surface may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material, or they may be formed by voids in the X-ray discernable material. According to another aspect, the peripheral surface may be formed from a radiotransparent or radiolucent material and applied with a radiopaque agent, and the X-ray discernable indicia may be one or more voids in the radiopaque agent or may be portions of the peripheral surface applied with the radiopaque agent.
